Benefits of technology

This solution enables efficient use of communications resources, allowing both types of reduced capability devices to operate within the same network without interoperability issues, optimizing bandwidth and reducing the complexity and cost of radio transceivers for MTC-type devices.

Problems solved by technology

Whilst it can be convenient for a terminal such as an MTC type terminal to take advantage of the wide coverage area provided by a third or fourth generation mobile telecommunication network, there are at present disadvantages and challenges to successful deployment.
Furthermore, while the type of functions performed by the MTC-type terminal (e.g. collecting and reporting back data) do not require particularly complex processing to perform, third and fourth generation mobile telecommunication networks typically employ advanced data modulation techniques (such as 16 QAM or 64 QAM) on the radio interface which can require more complex and expensive radio transceivers to implement.
However, there may different types of reduced capability devices and as a result a deployment of a mobile communications network which is configured to support one type of reduced capability device may not be compatible with another form of reduced capability device.

Example of an LTE System

[0028]FIG. 1 provides a schematic diagram illustrating some basic functionality of a conventional mobile telecommunications network, using for example a 3GPP defined UMTS and / or Long Term Evolution (LTE) architecture.

[0029]The network includes a plurality of base stations 101 connected to a core network 102. Each base station provides a coverage area 103 (i.e. a cell) within which data can be communicated to and from communications devices (also referred to as mobile terminals, MT or User equipment, UE) 104. Data is transmitted from base stations 101 to communications devices 104 within their respective coverage areas 103 via a radio downlink Data is transmitted from communications devices 104 to the base stations 101 via a radio uplink. The core network 102 routes data to and from the communications devices 104 via the respective base stations 101 and provides functions such as authentication, mobility management, charging and so on.

Abstract

A communications device is configured to receive data from a wireless access interface transmitted by a mobile communications network. The wireless access interface provides a plurality of communications resource elements within a system bandwidth providing a host frequency range of a host carrier and reserved communications resources for preferable allocation to reduced capability devices, the reserved communications resources forming a virtual carrier. In each of a plurality of time divided units, the wireless access interface provides a shared channel of communications resources and a control channel formed within the communications resources of the system bandwidth of the host frequency range for communicating resource allocation messages to communications devices. The resource allocation messages allocate the communications resources of the shared channel to the communication devices within the system bandwidth and allocate the reserved communications resources to the reduced capability devices.
